Control and/or signaling device for mounting in the mounting bore of a mounting plate

ABSTRACT

A control and/or signaling device including a housing member and a head member, and which is intended for mounting in the mounting bore of a mounting plate, a mounting wall or a like smaller than the head in the vicinity of the head. The housing member so that the control and/or signaling device can be attached through a nut member and using only one hand. To this end, a resilient flexible material is placed in the transition area between the cylindrical housing and the head member wherein this flexible mass is applied according to a dual-component injection-moulding method. The housing member and the head member are made of hard resilient material that has a sealing function as well as fixation function optimised by rib-shaped segments.

FIELD OF THE INVENTION

The present invention relates to a control and/or signaling device including a housing part and a head part for mounting in a mounting bore of a mounting plate and being secured with a nut part definition.

RELATED TECHNOLOGY

Control and/or signaling devices are usually provided with a threaded part and a nut part.

German Patent No. 3237589 C2, for example, describes a signaling device mounted with a nut part.

Two hands are needed to mount such control and/or signaling devices. While one hand holds the device securely, the nut part is screwed on with the other hand. An object of the present invention is to provide a control and/or signaling device including a housing part and a head part for mounting in a mounting bore of a mounting plate and being secured with a nut part where mounting is simplified by permitting mounting with one hand.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention provides a control and/or signaling device for mounting in a mounting bore, the device including a head part including a first hard elastic plastic material, the head part being larger than the mounting bore, and a housing part including a second hard elastic plastic material and including an outside thread in the vicinity of the head part so as to enable the control and/or signaling device to be secured with a nut part, the housing part being smaller than the mounting bore. The device also includes a flexible material disposed in a transition area between the housing part and the head part, the flexible material for forming a seal with the mounting bore, the flexible material including at least one rib-shaped segment for helping to secure the control and/or signaling device.

On the basis of the drawings, the present invention an, additional embodiments of and improvements on the present invention, and other advantages will be described and explained in greater detail.

DETAILED DESCRIPTION

FIG. 1 shows a control and/or signaling device 1 for mounting in a mounting bore of a mounting plate, mounting wall or the like.

Control and/or signaling device 1 includes a housing part 2 and a head part 3 which are labeled with the respective reference numbers in FIG. 1.

The mounting bore is smaller than the head part and larger than the housing part. Housing part 2 has two chord-like notches 9 for fastening with a U-shaped holding part (not shown in detail) near terminal clamps 16, as shown in FIG. 1.

A flexible material 5 is arranged in transition area 4 between cylindrical housing 2 and cylinder disc-shaped head part 3, the material being applied by a two-component injection molding method, whereas housing part 2 and head part 3 are made of hard elastic plastic compound.

Flexible material 5 has, in addition to the actual sealing function, a securing function which is optimized by rib-shaped segments 6 a, 6 b.

Segments 6 a are integrally molded radially on the outside, and are interrupted at regular intervals just below head part 3. In the area of these interruptions is arranged a second row of segments 6 b, but this is arranged closer to head part 3 and is offset vertically.

In mounting control and/or signaling device 1, segments 6 a or 6 b press against the edge of the mounting bore in such a way that the nut part can be tightened using one hand without having to hold control and/or signaling device 1 with the other hand.
